The Longest of Rivers

Did you know that the Missouri River is the longest river? Well, technically, the Nile River is the longest river in the world, stretching over 4,100 miles, however, the Missouri River is the longest river in the United States.

Even though the Missouri River is only half as long as the Nile River, the Missouri River is undoubtedly immense, spanning across 7 states. Assuming the average width of the Missouri River is 3,000 feet, the total area of the Missouri River is approximately 1,300 square miles, which is about the same area as the state of Rhode Island or Lake Iliamna in Alaska!

This is the final Onward American post of the year, and in honor of 2024, here is a list of the 24 longest rivers in the United States.
